Curry: proposed new functional programming, er, function.
Hi all (especially R-core) I suppose,
With the introduction of the new functional programming functions into
base I thought I'd ask for a Curry() function. I use a simple one that
looks this:
Curry = function(FUN,...) { .orig = list(...);function(...)
do.call(FUN,c(.orig,list(...))) }
This comes in really handy when using say, heatmap():

scoping/non-standard evaluation issue
Dear r-devel list members,
On a couple of occasions I've encountered the issue illustrated by the
following examples:
--------- snip -----------
> mod.1 <- lm(Employed ~ GNP.deflator + GNP + Unemployed +
+ Armed.Forces + Population + Year, data=longley)
> mod.2 <- update(mod.1, . ~ . - Year + Year)
> all.equal(mod.1, mod.2)
[1] TRUE

(no subject)
Dear all,
Is there a quick and easy way of converting utf characters to the \uxxxx
form (necessary e.g. for packages)? I mean something working like this:
> utf2uxxxx("õäöü")
[1] "\u00f5\u00e4\u00f6\u00fc"
It is easy to program but perhaps someone already has implemented this. (I
couldn't find anything useful from searches incl RSiteSearch).
Thanks in advance,
Kenn

sqlFetch (RODBC) question
Dear all,
I've used RODBC a lot to read in files created in MS excel and access but
found a strange problem today: a variable in my data file contained both
numbers and text; sqlFetch would set text within a row of numbers to NA; but
if first 5 or 6 rows would be text then all numbers would be read in as NA.

Preserving the class of POSIXt objects
Dear all,
I am working with a list of objects each of which contains two POSIXct
objects (say, $Start and $End) and a number of different data in
addition to that. Now an easy way to extract Start times of all object
could be sapply(x, "[", "Start") but this converts them all to
numeric, and so does sapply(x, "[[", "Start"). lapply preserves the
class but

ordisymbol - changing symbols used in plotting factor levels
Hello,
I'm trying plot points in an NMDS according to a factor with two levels:
fig<-ordiplot(canod.sol,
type="none",cex.axis=0.9,cex.lab=0.1,pty="m",tck=-0.01)
ordisymbol(fig, y = hab, factor = "habitat", rainbow = T,col = env,
legend = F)
This gets me part of the way - It produces a plot with blue triangles
for the first factor level and red circles

suggestions re trunc.POSIXt
Dear all,
I hope this is a right place to post this; r-help might be appropriate
but it looks like I'm suggesting a change in base package, so I
decided to post here. (+ Apologies if that has been changed recently
-- the version I'm using is R.2.12.2 on Windows.)
I've noticed an unexpected behavior of trunc.POSIXt:
foo <- seq(as.POSIXct( "2009-10-23 22:00:00"),

Notes and warnings in building a package ('ms-dos style file name', 'no visible binding' and using .C("bincount", ..., PACKAGE = "base"))
Dear all,
While buildign a package (R 2.15.2 on windows XP) I had three
warnings/notes -- I would be grateful for any hints on what to do.
1. The first one is probably not really important if I'm not missing
something:
cygwin warning:

Consecutive zeros in a vector
Suppose X is a long vector of integers (typically about 30000 elements). Is
there an efficient way to detect whether there are at least N consecutive
zeros in X, and if yes, where does this occur?
for example, suppose X is:
1 2 3 4 5 0 0 0 0 0 0 0 0 0 0 0 0 0 0 3 4 2 0 1 2 0 0 0 2 2 2 2 2 ...
and N is 10. I would like a foo(X, 10) to return something like c(6,19)

Needed: step-by-step HOW-TO for Smaba and Winbind in mixed environment
I need a document that will walk me (a Samba newbie) through a setup of samba and winbind in a mixed unix/linux/win2k environment. I am also looking for a linux/unix equivalent to 'network neighborhood' on Windows systems for some of my users.

New to samba Want to use samba as file/print servers for Win2K domain
I am new to Samba. I have a brand new win2K domain. I would like to
use Samba on RH7.2 systems to handle all of our file and print services.
Before implementing this, I would like to be prepared for the
installation. Where can I find information for implementing security on
a Samba files share using the Win2K Active Directory security system?
Will I need to implement kerberos or LDAP services

lm.ridge
Hello, I have posted this mail a few days ago but I did it wrong, I hope
is right now:
I have the following doubts related with lm.ridge, from MASS package. To
show the problem using the Longley example, I have the following doubts:
First: I think coefficients from lm(Employed~.,data=longley) should be
equal coefficients from lm.ridge(Employed~.,data=longley, lambda=0) why
it does not happen?

First Variable in lm
Hi all,
I just cannot think of how to do it:
I want to take the first variable (column) of a data frame and regress
it against all other variables.
bla <- function (dat) {
reg <- lm(whateverthefirstofthevariablenamesis ~., data=dat)
return(reg)
}
What kind of function do I have to take instead of the
whateverthefirstofthevariablenamesis,
eval(), substitute(), get(), ...

strucchange Nyblom-Hansen Test?
I want to apply Nyblom-Hansen test with the strucchange package, but I don't
know how is the correct way and what is the difference between the following
two approaches (leeding to different results):
data("longley")
# 1. Approach:
sctest(Employed ~ Year + GNP.deflator + GNP + Armed.Forces, data = longley,
type = "Nyblom-Hansen")
#results in:

hclust doesn't return merge details
Dear R-users,
I tried to receive the merge details of a clustering by using the
summary function of hclust.
For illustration I use the Longley data as done by Prof Ripley (Wed 11
Apr 2001)
d <- dist(longley.y)
d <- d/max(d)
hc <- hclust(d, "ave")
But instead of getting a matrix for $merge I get:

vcov and survival
Dear Terry,
Even the behaviour of lm() and glm() isn't entirely consistent. In both cases, singularity results in NA coefficients by default, and these are reported in the model summary and coefficient vector, but not in the coefficient covariance matrix:

> mod.lm <- lm(Employed ~ GNP + Population + I(GNP + Population),
+ data=longley)

improved pairs.formula?
Dear all,
I would like to suggest changing the pairs.formula command such that a
command like
pairs(GNP ~ . - Year - GNP.deflator, longley)
would behave in a similar fashion as
lm(GNP ~ . - Year - GNP.deflator, longley)
i.e., make a pairwise scatterplot of GNP and all other variables in
the (longley) dataframe except for Year and GNP.deflator. The above
command, with the

trimmed mean in R seems to round the trimming fraction
subject: trimmed mean in R seems to round the trimming fraction
to r-help at stat.math.ethz.ch.
Consider the following example of 10 numbers. 10% trimmed mean is correct
but you can see that the result is the same for many trimming fractions
till 0.20!
For example 13% trimmed mean should use interpolation of second and
eighth ordered observation. R does not seem to do this.

[LLVMdev] Problem linking and JITing code through C++-API
I have a frontend that generates some LLVM bitcode that needs to be linked with other bitcode (its runtime library), which I generate from C++ source using Clang.
If I write the output of my program to disk, link it with llvm-link, and then run it with lli, everything works perfectly. But if I try to perform the linking and running steps in my main program, I get this error during

seeking a help on if function
Hello r helpers! Below is the whole coding for my programme. Before proceed more further, let me explain for you. First of all, I need to compute trimmed mean. Till that step is ok. Then I need to compute ssdw which is sum of square deviation. If I do equal trimming at both tail of distribution that I chose, I will use the first ssd formulae which is "a". But if I am doing unequal
